This manuscript describes an airborne SAL system for remote targets imaging. We have recently completed an experiment of ISAL at 1.1 km outdoor using the system. Relative motion was provided by a rotating platform with three cubes on while the SAL system kept stationary. System, signal collection, processing and the results are described in the paper. The result showed that the system had the ability to image for moving targets. Accurate rotating platform and complex target will be used to achieve further ISAL experiments on the next stage.
